304 Stainless vs Aluminum
There are several reasons why we came out with a stainless steel line. The main reason is that 304 stainless will offer the best level of protection against thieves and galvanic corrosion.
Whether you choose a stainless steel or aluminum shield, you will not need to worry about overheating. Our products are tested to ensure there are no adverse impact to your converters.

Here are a few facts about stainless steel and aluminum. Check out our stainless steel line here.
- Strength, density, weight. Stainless steel has about twice the tensile strength of aluminum, making it harder to cut, bend, and warp. It is about 2.5 times more dense than aluminum and about three times as heavy. Our stainless shields are about twice as heavy as our aluminum ones depending on the application (4lbs vs 2lbs).
- Corrosion. While both stainless steel and aluminum have anti-corrosive properties, we use zinc-coated rivet nuts to protect against galvanic corrosion. Whenever there is a drilled hole in the steel frame of the vehicle, the frame looses its protective coating and can accelerate corrosion. Whenever possible, we design our shields without drilled holes, but whenever our products need a drilled hole, we protect the vehicle with our zinc-coated rivet nuts.
- Thermal properties. In temperatures of excess of 400 degrees, aluminum becomes very soft. If you encase a converter in aluminum, you will easily reach these temperatures. Our aluminum designs ensure the shields are adequately ventilated and tested to make sure they do not cause excessive build up of heat.
- Thermal conductivity. Aluminum has a better thermal conductivity than steel. This means that aluminum will heat up quicker than steel. However, neither materials will impact the temperatures around the converter due to our heat ventilation features.
